4-minute leave-in treatment to clinically reverse hair damage
An at-home leave-in treatment infused with our patented K18Peptide™ that works to repair even the most extreme damage, renewing hair to its most youthful, healthy state.
Traveling deeper into the inner layers of hair than traditional repair products, our revolutionary patented K18Peptide™ is just the right size and makeup to fit in and reconnect broken keratin chains, renewing hair with strength, softness, smoothness, and bounce. You can feel and see the difference with the first use.
See dosage chart for exact usage. For best results, use for the first 4-6 consecutive washes, then every 3-4 washes as needed to maintain hair strength.

do's + don'ts
DO use a clarifying shampoo if you’re a heavy product or dry shampoo user to remove buildup and help our peptide penetrate and get where it needs to go.
DO wait the full 4 minutes before styling or applying other product
DO use every 4-6 shampoos consecutively to see and feel ongoing results
DON’T condition your hair before application (trust us, most won’t need it after K18, if you still need, add a leave-in after the 4-minute window is up post-application)
DON’T overuse, a little goes a long way.
DON’T rinse out. This is a leave-in, so you know, leave it in!
